Notes
5.
Not measured in production.
6.
InH=bus current at DnH, InL=bus current at DnL
7.
VDnD=VDnH-VDnL
8.
Max VDnD = VSUPn - 2 * VMID_OFFSET - VDnD(Drop), VMID_OFFSET = |VMID - VSUPn / 2|
9.
Worst Case Disabled Low Side Bus Leakage for DnL occurs with DnL = VSUP and DnH = 0V. In this configuration, the DnL leakage
current can exceed 1mA. This is not measured in production.

≤ VCC ≤ 5.25V, 9.0V ≤ VSUPn ≤ 25V,-40°C ≤ TA ≤ 90°C, unless otherwise
noted. Voltages relative to GND, unless otherwise noted. Typical values noted reflect the approximate mean values of the
parameter at TA = 25°C under nominal conditions, unless otherwise noted.
